BRAKE.

SPECIFICATION forming part of Letters Patent No. 781,953, dated February'7', 1905.

Application filed August 3, 1904. Serial No. 219,329.

To 11]] 11/7/0712 it 712/11 cone/1771.-

Be it known that l, Sunsueazmu KENXEDY, a citizen of the United Statesof America, residing at River-view, in the county of Washington andState of Pennsylvania, have invented certain new and useful Improvementsin Brakes, of which the following is a speciiication, reference beingbad therein to the accompanying drawings.

This invention has relation to car-brakes, and relates in particular tohand-operated brakes for street-cars.

The invention has for its object the provision of a novel brake adaptedto simultaneously operate upon the treads of the wheels of the car andthe tread of the rails upon which said wheels run.

Briefly described, my improved car-brake comprises a shoe which isadjustably mounted in front of the rear wheels of a car, these shoesbeing so constructed as to engage the tread of the wheel and the treadof the rails, and to the car-body I secure hangers which support saidshoes and the mechanism employed to operate the same.

The car-brake and its appurtenant parts are so constructed that they maybe readily placed upon the ordinary form of car, and the brake isadapted to be operated by the motorman of the car from the frontplatform thereof.

My invention further consists in the novel construction, combination,and arrangement of parts to be hereinafter more fully described.

Referring to the drawings accompanying this application, Figure 1 is afragmentary side elevation of a car having my improvements appliedthereto. Fig. :2 is a front view of one of the hangers. Fig. 3 is asimilar view of another hanger forming a part of my improved car-brake.Fig. l is a front view of one of the shoes, and Fig. 5 is a bottom planview thereof.

Throughout the several views of the drawings similar reference-numeralsdesignate corresponding parts.

The reference-numeral 1 indicates the ordinary character of car which iscommonly used, this car being mounted upon the wheels 2 2. Mounted uponthe forward platform a rod l, which is braced by a guide-yoke 5, and therod extends downwardly through the platform and has connected to itslower end a cable or rope 6, while a suitable crank-hamlle T is securedto its upper end. Upon the bottom of the car I fix hangers 8 and 9, thehanger 9 being mounted directly in front of the rear axle and in frontof each rear wheel. The hanger 8 is provided with a T-shaped pivotedlever 10 and with a rearwardlyextending yoke 11, to the cross-bar IQ ofwhich is connected a spring it, the other end of this spring beingsecured to the depending portion of the T- shaped lever 10. In the yoke9, preferably near the bottom of the car, is rotatably mounted a pulley15. over which passes the cable or rope 6, which has its loose endconnected to the depending portion ofthe T-shaped lever 10.

Near the lower end of the hanger .3 is journaled a roller 16, and uponthis roller rests and reciproeates a rod 17, the one end of which isconnected to the depending portion of the T- shaped lever, as designatedat 18, while the other end thereof is pivotally mounted in the lugs 1919 of the shoe 20. This shoe is segmental in form, and the curvedportion 21 of the shoe is described upon an arc coinciding to thewriphery of the tread of the wheels .2. The one side of the shoe isprovided with a depending lug 22, which is adapted to engage the side ofthe tread of the rail and guide the shoe in its movement over said rail.The under face of the shoe corrugated, as designated by the referencenumeral 21, whereby it will firmly grip the tread of the rail.

In operation when the rod is rotated by the motorman the cable, rope, orchain 6 is wound upon the lower end of the rod, this operation drawingthe depending portion of the T-shaped arm rearwardly, expanding thespring H and forcing the rod 17 rearwardly, this red causing the shoe 21to impinge between the tread of the rail and the tread of the wheel, andupon a further movement of the car the wheel will ride upon the shoe andthe weight of the car will cause the corrugations or roughened portionof the shoe to engage the tread of the rail, causing the car to slackenits speed until the same has stopped. To again place the car inoperation, thesaine is moved rearwardly until the wheels have passed oflof the shoes, and upon the motorman releasing the rod 4: the contractionof the springs will withdraw the shoe from engagement with the rail.

Hy improved brake is particularly adapted to be used in connection withinclined railways and the like, and by providing a brake which willsimultaneously engage the tread of the wheels and the tread of the railsa very effective means is provided for stopping the car.

It will be observed that I have only illustrated one of these shoes inconnection with the car; but I wish it to be understood that a shoe isemployed upon each side of the car directly in front of the rear wheels,and I may make changes in the general arrangement of the hangers withoutdeparting from the scope of the invention.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a device of the character described, the combination with a car, abrake-rod mounted on the platform of the car, a hanger mounted on thecar, and having a rearwardly-extending yoke, a T-shaped lever journaledin said hanger, a spring interposed between said lever and yoke, asecond hanger mounted on the car, a wedge-shaped shoe adapted to contactwith the wheel of the car and the track, a rod passing through saidlast-named hanger and connected to said lever, a pulley in saidlast-named hanger, and a flexible connection attached to said lever andto said brake-rod and passing over said pulley.

2. In a device of the character described, the combination with a car, abrake-rod on the car and two hangers carried on the bottom of the car,of alever pivotally suspended in one of said hangers, a spring adaptedto force said lever in one direction, a flexible connection attached tosaid lever and said brakerod to draw the lever in the other direction, awedge-shaped shoe adapted to contact with the tread of a wheel of thecar, and the rail, and a rod connected to said shoe and to said leverand passing through the other of said hangers at an angle, the said shoebeing drawn up from the track and away from the wheel by the movementwhich is imparted to said lever by said spring.

in testimony whereof I affix my signature in the presence of twowitnesses.
